Corrosion in Super Critical CO2

There are several models that are focused on the corrosion rate prediction of carbon steel in aqueous environments that have dissolved CO₂.  However, none of the models are capable or equipped to deal with corrosion in condensed phase CO₂.  The current effort is focused on understanding the effect of various additions/impurities on the conditions where condensed phases are formed and determine the composition.  This paper will present data using OLI tools to understand the behavior of dense phase CO₂ and the role of various impurities on the conditions where condensation occurs as well as determining the composition of the condensate phase.  Experimental data on the corrosion rate of carbon steel in super critical CO₂ as a function of impuritiy additions like distilled water, amines, acids, and bases will also be presented.
